Question

如何禁用弹出菜单项，例如选择、全选、建议...、定义 (在 UIWebView) 上？

我在帮助上找到了以下信息，但不明白如何使用:

For the editing menu commands, this is the shared UIApplication object. Depending on the context, you can query the sender for information to help you determine whether a command should be enabled.

调整以下方法:

#import "NSObject+myCanPerformAction.h"

@implementation NSObject (myCanPerformAction)

- (BOOL)myCanPerformAction:(SEL)action withSender:(id)sender {
    if (action == @selector(copy:)) {
        return [self myCanPerformAction:action withSender:sender]; // not a recursion
    }
    if (action == @selector(paste:)) {
        return [self myCanPerformAction:action withSender:sender]; // not a recursion
    }
    return NO;
}

@end

混合:

[[UIWebDocumentView class] jr_swizzleMethod:@selector(canPerformAction:withSender:) withMethod:@selector(myCanPerformAction:withSender:) error:nil];
